The heat pump has more to do with getting off gas and oil and other hydrocarbons that are burned at the house, and switching all your energy usage over to electricity, which can either be efficiently generated elsewhere, or allow you to go completely off the grid.

Don't do it today to save money today. Do it to save the planet and help ensure that you're not beholden to $9000/hour bills because the people selling you the precious hydrocarbons have you backed into a corner that you cannot possibly dig yourself out of.

You know, so like you can't be screwed by the like of ERCOT when they tell Texans "oh, that sure is a nice grid you've got there. It would be a real shame if it were to be shut down simply because some of the electrical generating plants haven't been properly weatherized. Hmm, I wonder how many of these plants we should take offline on the coldest day of the year????"
